| Realization of Carrier Synchronization in Telemetry |
|
| () |
| Abstract: |
| Synchronization is very important in communication, there are many methods for carrier synchronization in which Costas Loop is particularly in common use. In this paper, the realization of inphase-orthodoxy Loop in telemetry is described and necessary analysis of the result of experiment in contrast with the simulation result in SystemView is made. Particularly, it makes emphatic explaination to the mathmodel of loop-filter. |
